Description

Technical Field

[0001] The invention relates to the technical field of water resource engineering, in particular to a rainwater grate of a plateau-plain water resource diversion device. Background Art

[0002] Floods often originate in mountainous areas. The rainwater received by each mountain converges into streams and eventually flows into the branches of the drainage paths used by the contiguous mountains. The fall flow in mountainous areas cannot be stopped artificially due to its natural characteristics. Proper management of plateau water flow is the key to the complete utilization of natural water resources by rainwater resource projects. However, for plain areas, whether their rainwater resource projects can effectively receive the concentrated water in the plateau drainage paths poses a severe test to the receiving capacity of the drainage ditch.

[0003] As time goes by, the phenomenon of "nine droughts in ten years" has made many flood ditches lack practical functions. Although humans are well aware of the disastrous consequences of droughts and floods caused by abnormal climate, and dare not easily change the basic structure of mountain flood ditches, people still carry out extensive tidying and modification of the walls of mountain flood ditches. This measure is mainly to obtain clearer water sources and prevent soil from being lost with water. However, it is worth noting that when people modify the walls of the ditches, they often ignore the tidying of the bottom of the ditches. Due to its soft soil, the bottom of the ditches grows plants and accumulates garbage all year round. These plants and garbage become lush and fertile under the nourishment of mountain water.

[0004] The water problem of people at the foot of the mountain is mainly solved by flood ditches. However, this long-term reliance on flood ditches inevitably leads to soil pollution in the ditches. When mountain water flows down, it is directly affected by the polluted soil in the ditches.

[0005] In view of the complexity of plateau topography and geology and the natural flow characteristics of the erratic instantaneous rainfall, disaster prevention work must be rigorous and meticulous. The main task of rainwater resource engineering in connecting the plateau section of the water resource diversion system in the plain area is to avoid disasters caused by the change of water flow patterns caused by terrain changes.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] It should also be noted that the following specific embodiments or specific implementations are a series of optimized settings listed in the present invention to further explain the specific content of the invention, and these settings can be used in combination or in association with each other.

[0025] like Figure 1-3 The figure shows a water resource diversion device disclosed in the prior art, including: a flood discharge ditch 1, downstream rainwater 2, a sidewalk 3, a highway 4, an original domestic sewage pipe 5, ditch side land 6, and a permeable grate 7. The flood discharge ditch 1 is connected to the downstream rainwater 2 originating from the plateau path. During operation, the flood discharge ditch 1 maintains a constant cross-section and capacity to ensure smooth reception and guidance of plateau potential energy water. If the flow of the downstream rainwater 2 is small, when it reaches the flood discharge ditch 1 in the plain section, the water flow may be rapidly reduced due to the absorption of the soil and plants at the bottom of the ditch, and it may even be difficult to detect its existence. However, if the flow of the downstream rainwater 2 surges to a disaster level, due to the lack of shape adjustment in the ditch design, and the natural slowdown of the flow rate when the high mountain potential energy water is converted into horizontal flow, the excessive downstream rainwater 2 will cause serious overflow at the junction of the plateau discharge path and the flood discharge ditch 1 in the plain, directly scouring the environment under the land slope, causing serious disasters and causing serious losses.

[0026] Example 1 In order to solve the problems existing in the water resource diversion device in the prior art, the present application discloses a plateau-plain water resource diversion device.

[0027] Mountains are the most ideal places for water accumulation in nature. When mountain water flows through the mountain and reaches the junction of the foot of the mountain and the plain land, the flow speed will naturally slow down. Because the water flow slows down when it first reaches the plain, the subsequent mountain potential energy water gradually superimposes on the plain land, forming an expanding beach. If the water flow area out of the beach is not dredged and treated in time, the continuous mountain potential energy water will accumulate at the junction of the plain land, eventually forming a flood. The water will continue to spread with the help of the terrain until it cannot be controlled.

[0028] In dry years, if the rainwater resources accumulated in the mountains are not properly collected, these slow-flowing and limited mountain water will soon be absorbed by the soil and plants in the ditch, and eventually disappear without a trace with the evaporation of the environment and climate. In rainwater resource projects, water resource diversion devices in plains and plateaus should follow the laws of natural water flow to ensure the effective use of water resources and environmental protection.

[0029] like Figure 4-8 20-21 show a plateau-plain water resource diversion device disclosed in the present application, including a flood discharge ditch 1, a pebble pit 11, a grate 12, a rainwater water delivery pipeline 9, a sewage water delivery pipeline 10, a water diversion baffle 50, a water receiving gate 14, a switch door chamber 15 and a pipeline port 16; the grate 12 includes a first grate 12a and a second grate 12b; the flood discharge ditch 1 is an expanded structure; the rainwater water delivery pipeline 9 is arranged above the sewage water delivery pipeline 10; a pebble pit 11 is arranged at the entrance of the sewage water delivery pipeline 10, and a plurality of pebbles 13 are arranged in the pebble pit; the first grate 12a is arranged at the edge of the pebble pit to limit the entry of pebbles 13 and impurities in the water body The rainwater conveying pipeline 9 and the sewage conveying pipeline 10; the water collecting gate 14 is arranged on the mesh, and its position height corresponds to the rainwater conveying pipeline 9; the water diversion baffle 50 is a detachable central vacant triangular enclosure, which is used to introduce water into the pebble pits 11 on both sides and into the rainwater conveying pipeline 9 and the sewage conveying pipeline 10; the inlet ends of the rainwater conveying pipeline 9 and the sewage conveying pipeline 10 are pipeline openings 16; a switch door chamber 15 is arranged between the rainwater conveying pipeline 9 and the water collecting gate 14; the water collecting gate 14 is arranged on the side wall of the switch door chamber 15 through a hinge 21; the water collecting gate 14 is provided with a switch door rope pull hole 37 and a door lock ring 23.

[0030] The establishment of the water diversion baffle 50 is intended to effectively solve the flood and drought problems for this engineering system. For flood and drought situations without potential energy flow, it is only necessary to ensure that the rainwater conveying pipeline 9 is facing the flowing water so that water can flow into the pipeline naturally. However, when facing natural forces such as floods and wind, various factors must be considered comprehensively and carefully to avoid greater catastrophic accidents caused by improper design. The newly established rainwater conveying pipeline 9 on both sides of the flood discharge ditch 1 is intended to receive the water falling from the plain expansion area and to deal with the flowing water carrying a variety of environmental items and potential energy in the mountain environment. According to the characteristics of potential energy flowing water, the flowing material is entrained the most on both sides of the water surface and the flow rate is slower, while the material is entrained less and the flow rate is faster in the middle of the water surface. In view of the principle that "the clearer the water, the better the flow performance", on limited rainy days, the rainwater conveying pipeline 9 cannot just wait to collect rainwater. If the collected water volume is insufficient due to climate and other reasons, the internal environment of the pipeline may be damaged. Therefore, a pebble pit 11 is set at the bottom of the flood discharge ditch 1 at the front end of the water collection gate 14 of the rainwater conveying pipeline 9. The downhill flood is difficult to intercept directly due to its potential energy, but the pebbles 13 are placed in the pit, and the water will flow into the pit first after hitting the pebbles. Only when the amount of water in the pit reaches a certain level, will a horizontal flow be formed and flow to the water collection gate 14. The hinge 21 of the water collection gate 14 is installed on the side wall of the switch door chamber 15. Two switch door rope pulling holes 37 are respectively provided above and below the door surface of the water collection gate 14, so as to facilitate the balanced switch operation of the door through the rope. In addition, the door lock ring 23 is installed at the upper and lower positions of the side frame of the door body to ensure the stable locking of the door. These pebbles 13 not only help the water collection gate 14 to reduce the impact force of the water flow, but also cooperate with the mesh 12 to leave the debris entrained in the downstream rainwater 2 in the newly set reserved space of the flood discharge ditch 1, thereby naturally reducing the volume of the subsequent water flow and preventing the water quality from being further polluted. This design helps to reduce the difficulty of water pollution control and environmental protection. When the water potential is small, a water diversion baffle 50 is set to allow all the water to enter the rainwater water delivery pipe 9 and the sewage water delivery pipe 10, which can prevent the water from volatilizing or entering the soil during water transportation, which is conducive to water collection. When the water potential is large, the water diversion baffle 50 is removed so that the water can be discharged from the middle flood discharge ditch 1. The main function of the water baffle 50 is to block the ditch cross-section directly opposite the original flood discharge ditch 1 and limit its capacity. At the same time, the newly widened rainwater water delivery pipes 9 on both sides can naturally slow down, receive and respond to problems such as sudden flood water volume. When the flood flows to the expanded area section, its flow rate will naturally slow down, and then pass through the selection and filtration of the pebble pit 11 and the mesh 12, and then enter the rainwater water delivery pipe 9. The rainwater 2 flowing down from the mountain environment is regulated and sorted by the facilities and devices in the engineering system of this case, so that it can maintain high quality and then smoothly enter the subsequent water delivery project to ensure that no unexpected situations occur. The entire process not only ensures the stability and safety of water flow, but also delivers high-quality water to areas in need, ensuring a long-term supply of water.

[0031] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) By setting up the pebble pit and the mesh, the technical scheme can effectively collect the water falling from the plain expansion area and filter out the impurities in the water body, thereby improving the collection efficiency and cleanliness of water resources. (2) By introducing the water diversion baffle, the technical scheme can flexibly adjust the flow direction and flow rate of the water flow, which can not only ensure that all the water enters the water transmission pipeline when the water potential is low to avoid the volatilization or loss of the water body, but also remove the water diversion baffle to discharge the excess flood water when the water potential is high, thereby enhancing the ability to respond to sudden flood water. (3) The design of the expanded flood discharge ditch structure and the pebble pit effectively reduces the flow rate of the flood. At the same time, the filtering effect of the pebbles and the mesh is utilized to reduce the impurities in the water flow, optimize the water flow structure, and ensure the smooth progress of the subsequent water transmission project. (4) The design of the water collection door, especially the setting of the opening and closing door rope pull hole and the door lock ring, can open and close the door automatically without the need for personnel to operate the door, thereby ensuring the flexibility and safety of the system operation. At the same time, the design avoids the need to quickly close or open the water collection gate during maintenance or in an emergency. (5) Through the filtering effect of the pebble pit and the mesh, as well as the separation design of the rainwater and sewage pipes, the technical solution can ensure the quality of the collected water resources, reduce the difficulty of subsequent water pollution control, and is conducive to environmental protection and sustainable use of water resources. (6) By introducing a variety of structures and equipment, such as water diversion baffles, pebble pits, mesh grates, etc., the technical solution enhances the natural adaptability and reliability of the system, enabling it to cope with water flow changes under different environmental conditions and ensure the stable operation of the system.

[0032] like Figure 8 , 9 , 19 is a further embodiment of the present application, further comprising a water filter plate 18, a floating object lifting chamber 19, a blocking plate 48 and a two-chamber partition 17; a water filter plate 18 is also provided on the first mesh screen 12a corresponding to the height position of the sewage water conveying pipe 10; a floating object lifting chamber 19 is provided between the water filter plate 18 and the sewage water conveying pipe 10; the floating object lifting chamber 19 and the switch door chamber 15 are separated by the two-chamber partition 17; a blocking plate 48 and a second mesh screen 12b are provided on the side of the floating object lifting chamber 19 close to the sewage water conveying pipe 10; the blocking plate 48 is provided below the second mesh screen 12b; a drainage hole 49 is provided on the blocking plate 48.

[0033] A mesh screen 12 is arranged on the water outlet surface of the pebble pit 11, followed by a water filter plate 18, which is used to further filter water quality and gravity. After the water filter plate 18, a floating object lifting chamber 19 is arranged, and its rear wall is composed of a plugging plate 48, and behind the plugging plate 48 is a newly installed sewage water delivery pipeline 10. There are two drainage holes 49 at the lower end of the plugging plate 48, and a permeable second mesh screen 12b is installed at the upper end of the plugging plate 48. The plugging plate 48 controls the lifting and lowering of the floating plate 32 in the floating object lifting chamber 19. The top plate of the floating object lifting chamber 19 is separated by a two-chamber partition 17. For the downflowing rainwater 2, it first flows to the water collection gate 14. The water collection gate 14 uses natural hydraulic force to open the door body toward the pipeline. Outside the water collection gate 14, a mesh screen 12 is also arranged, which not only protects the door body but also plays a role in filtering water. In this way, the volume and potential energy of rainwater entering the rainwater conveying pipe 9 are reduced, thereby accelerating the flow rate and reducing destructiveness, ensuring the long-term and stable operation of the water collecting gate 14. In order to match the square water collecting gate 14 with the circular rainwater conveying pipe 9, a switch door chamber 15 is set in front of the rainwater conveying pipe 9. The bottom plate of the chamber is the top plate of the floating object lifting chamber 19, which is separated by two chamber partitions 17. The water collecting gate 14 is installed on the side wall of the switch door chamber 15 through a hinge 21, and a locking door ring 23 is provided to prevent wind damage to the water collecting gate 14. It is worth mentioning that the pebbles 13 in the pebble pit 11 are an excellent natural water filtration material. After being filtered by the pebbles 13, the downstream rainwater 2 directly enters the floating object lifting chamber 19, providing a high-quality water source for subsequent water delivery work.

[0034] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) By setting a water filter plate and a floating object lifting chamber in front of the sewage water delivery pipeline, combined with the use of a pebble pit and a mesh, the present technical scheme can effectively filter out impurities and floating objects in the water body, significantly improve the cleanliness of the water quality, and provide a high-quality water source for subsequent water delivery projects. (2) The design of the floating object lifting chamber, combined with the configuration of the blocking plate and the drainage hole, can flexibly regulate the water flow to ensure that the system can operate stably and efficiently under different water potentials. This design is particularly suitable for the complex and changeable hydrological environment in plateau-plain areas. (3) The mesh set outside the water collection gate not only plays a role in filtering water, but also protects the water collection gate from the impact of debris in the water flow, thereby extending the service life of the water collection gate. At the same time, the installation of the hinge and the design of the door lock ring also enhance the stability of the water collection gate, further preventing the water collection gate from being damaged by natural factors such as wind. (4) By rationally arranging the various components, this technical solution optimizes the water flow structure, allowing the water to flow smoothly and stably in the system, reducing the impact and destructiveness of the water flow, and ensuring the stable operation of the entire system.

[0035] like Fig. 9 , 10, 12-16, 42 show further embodiments of the present application, further comprising a floating plate 32, a spring 30, a barbed lock hook 41, a lock-releasing rope 39 and a rod body; the rod body comprises: a hook-releasing rod 26, a lock hook rod 27, a door-closing rope rod 28a, a door-opening rope rod 31 and a spring-stabilizing rod 29; the door-opening rope rod 31 has two, namely a first door-opening rope rod 31a and a second door-opening rope rod 31b; the second door-closing rope 20b on the floating plate 32 combines with the door-closing rope rod 28a and the first door-closing rope 20a tied to the rod and has the same moving distance; the The floating plate 32 is arranged in the floating object lifting chamber 19; the unloading hook rod 26, the locking hook rod 27, the door closing rope rod 28a, the second door closing rope 20b, the door opening rope rod 31 and the stabilizing spring rod 29 are arranged on the floating plate 32; the stabilizing spring rod 29 is sleeved with a spring 30; the end of the locking hook rod 27 is provided with a locking hook 41; the end of the unloading hook rod 26 is connected to the locking hook 41 through the unloading lock rope 39; the two-chamber partition 17 is provided with perforations corresponding to the rod body and the rope; the perforations include: the unloading hook rod perforation 36, the locking hook rod perforation 38, the closing rope 20b, the door opening rope 31, and the stabilizing spring rod 29. The door rope hole 34, the door opening rope hole 33, and the spring stabilizing rod through hole 35 are respectively used to allow the unhooking rod 26, the locking hook rod 27, the door closing rope rod 28a, the second door closing rope 20b, the door opening rope rod 31 and the spring stabilizing rod 29 to pass through; the door opening rope hole 33 has two holes, namely, the first door opening rope hole 33a and the second door opening rope hole 33b; the first door opening rope rod 31a passes through the first door opening rope hole 33a; the second door opening rope rod 31b passes through the second door opening rope hole 33b; the door closing rope hole 34 has two holes, namely, the first door closing rope hole 34a and the second door closing rope hole 34b. Rope hole 34b; the door-closing rope rod 28a passes through the first door-closing rope hole 34a; the second door-closing rope 20b passes through the second door-closing rope hole 34b; each through-hole on the two-chamber partition 17 is provided with a hollow screw 42; nuts 43 are provided at both ends of the hollow screw 42 for fixing the hollow screw 42 on the two-chamber partition 17; all rod bodies are also provided with plastic film bags 44, and the plastic film bags 44 passing through the second door-closing rope hole 34b and on the second door-closing rope 20b are tied together with a strap rope 45.

[0036] The two diagonal positions of the floating plate 32 are mainly equipped with door opening and closing structural components. Specifically, the unhooking rod 26, the locking hook rod 27 and the door closing rope rod 28a are installed on the plate corner on one side; and the two door opening rope rods 31 are installed on the plate corner on the other side opposite to it. In addition, the structural components for balancing the force of the floating plate are arranged at the other two diagonal positions of the floating plate 32. Specifically, the stabilizing spring rod 29 is set on the plate corner on one side, and the spring 30 is sleeved outside the stabilizing spring rod 29; and the second door closing rope 20b and the stabilizing spring rod 29 are installed on the plate corner opposite to it, and similarly, the spring 30 is also sleeved outside the stabilizing spring rod 29. The upper ends of the rod heads of the unhooking rod 26, the door closing rope rod 28a and the door opening rope rod 31 are all tied with their respective required pull ropes for easy operation and control. It is worth noting that the rod head of the locking hook rod 27 is not tied with a pull rope, but is directly connected to the barb lock hook 41 to ensure the stability of the locking. In particular, the rod head of the unhooking rod 26 is not only tied with a lock unloading rope 39, but also the other end of the lock unloading rope 39 is connected to a lock hook 41. This design makes the lock unloading process more convenient and safe. In summary, as the core component of the engineering system of this case, the floating plate 32 has a high degree of professionalism and practicality in its structural design and functional configuration, ensuring the efficient operation and stability of the entire system. The two-chamber partition 17 is fixed to the upper end of the floating plate 32 as the top plate of the floating object lifting chamber 19 and the bottom plate of the door opening and closing chamber 15. The floating rods and the second door closing rope 20b on the floating plate 32 can only move up and down. In order to optimize the righting and stabilizing performance of the floating rod, a corresponding perforated structure is set on the two-chamber partition 17. These perforations are the best adaptation design to ensure that the floating rod works smoothly. On the diagonal side of the two-chamber partition 17, there are unhooking rod perforations 36, lock hook rod perforations 38 and the first door closing rope hole 34a. On the other side of the plate corner opposite to this, two opening rope holes 33 are arranged side by side. In addition, on one side of the plate corners on the other two diagonal corners, a spring rod through hole 35 is arranged, and on the opposite plate corner, a second closing rope hole 34b and another spring rod through hole 35 are arranged. Each through hole on the two chamber partitions 17 is equipped with Fig.13 and 16The hollow screws 42 shown in the figure have nuts 43 at both ends that can be tightened. These perforations correspond to the floating rods and ropes on the floating plate 32 one by one, and the floating rods can move freely up and down in the hollow screws 42. As the bottom plate of the switch door chamber 15, the two-chamber partition 17 is subjected to the impact and washing of the not-so-clear and chaotic water in the filtering environment. In order to prevent the impurities in the water from being deposited and jamming the floating rods and ropes that need to be moved, we have taken the following measures: first, use a plastic film bag 44 to wrap each rod, and then use a strap rope 45 to tightly bind one side of the bag opening of the plastic film bag 44 to the rod head of each rod, or tie the drawstring tied to the connecting rod together; then, put the remaining bag opening of the plastic film bag 44 on the hollow screw 42 of the two-chamber partition 17, and use a nut 43 to tightly fix the bag opening of the plastic film bag 44 to the hollow screw 42. Similarly, the rods and ropes under the two-chamber partition 17 can also be covered with a plastic film bag and tightly fixed in the same way. This design ensures that the floating rod and rope will not be adversely affected by the chaotic water when moving in the plastic film bag 44. The floating plate 32 has a significant balanced buoyancy characteristic. However, in the structural design, the force is applied only through the two diagonal corners of the floating plate 32, and the remaining two diagonal corners do not bear the force. In the case of no additional force, the stability of the floating plate is ensured by adding a balancing device, that is, a stabilizing spring rod 29, to the diagonal corners of the floating plate 32. The stabilizing spring rod 29 is covered with a spring 30, which enables the stabilizing spring rod 29 to move synchronously with other floating rods according to the size of the force, thereby achieving four-corner balance of the floating plate 32 during the rising and falling process. This design ensures that various types of floating rods and ropes can operate naturally and stably during operation.

[0037] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) The movement of the floating plate can be accurately controlled by the rod body and rope structure and the supporting perforation system. The rod body includes a hook removal rod, a hook locking rod, a door closing rope rod, a door opening rope rod and a spring stabilizing rod, which are fixed to the two-chamber partition by hollow screws and nuts to ensure that the floating plate is stable and smooth when moving up and down. (2) The design of the spring stabilizing rod is used in conjunction with the spring to provide additional balancing force for the floating plate, ensuring that the four corners of the floating plate are balanced during the rising and falling process, effectively preventing the system from becoming unstable or damaged due to uneven force. (3) The use of plastic film bags to wrap each rod and rope not only protects the rod body and rope from the influence of water quality, but also facilitates the cleaning and maintenance of the system.

[0038] like Fig. 9 , 1017 and 18 show further implementations of the present application, wherein the top of the switch door chamber 15 is the switch door chamber ceiling 46, and the side wall thereof is the switch door chamber side wall 47; three hanging rope loops 24 are installed on the switch door chamber ceiling 46; the positions of the three hanging rope loops 24 correspond to the positions of the first door opening rope hole 33a, the first door closing rope hole 34a and the unhooking rod through hole 36 on the chamber partition 17 respectively; a stabilizing rope loop 25 is provided on the switch door chamber side wall 47.

[0039] A rope ring 24 has been installed on the roof 46 of the switch door chamber, which is intended to prevent the impact of flood water on the rope and ensure that the working efficiency of the rope is not affected. Specifically, a rope ring 24 on the roof 46 needs to be installed in correspondence with a door opening rope hole 33 on the two-chamber partition 17; at the same time, another rope ring 24 also needs to correspond to the first door closing rope hole 34a on the partition 17; and another rope ring 24 needs to correspond to the unhooking rod through hole 36. Regarding the position layout of the stabilizing rope ring 25 on the side wall 47 of the switch door chamber, the working efficiency of this engineering system mainly depends on the energy buoyancy provided by the floating plate 32, the hard directional movement of each floating rod, and the structural transmission function of the rope. The lock door ring 23 installed on the edge of the door side frame, due to the soft characteristics of the rope, when the lock hook 41 autonomously confirms the position of the lock door ring 23, it needs to use the assistance of the stabilizing rope ring 25 to ensure that the lock hook 41 can accurately penetrate into the lock door ring 23. Therefore, the stabilizing rope ring 25 must be installed at the upper end of the unhooking rod hole 36, and also needs to obtain the additional support of the hanging rope ring 24 on the top 46 of the switch door chamber.

[0040] like Figure 9-13 The figure shows a further embodiment of the present application, wherein there are two door opening and closing rope pulling holes 37, which are respectively arranged at the upper end and the lower end of the water collecting door 14; the first door opening rope rod 31a and the second door opening rope rod 31b are respectively tied with the first door opening rope 22a and the second door opening rope 22b; and a rope pressing ring 40 is arranged next to each door opening rope hole 33; The first door-opening rope 22a and the second door-opening rope 22b pass through two rope pressure rings 40 respectively; the first door-opening rope 22a passes through the rope suspension ring 24 installed on the top 46 of the door-opening chamber corresponding to the first door-opening rope hole 33a, and continues to pass through the door-opening rope pulling hole 37 at the upper end of the water-collecting door 14 and is fixedly connected to the door-opening rope pulling hole 37; the second door-opening rope 22b passes through the door-opening rope pulling hole 37 at the lower end of the water-collecting door 14 and is fixedly connected to the door-opening rope pulling hole 37; a rope pressure ring 40 is arranged next to the first door-closing rope hole 34a; the door-closing rope rod 28a is fastened with the first door-closing rope 20a; A closing rope 20a passes through the rope ring 24 corresponding to the position of the first closing rope hole 34a, and continues to pass through the switch rope hole 37 at the upper end of the water collecting gate 14, and is fixedly connected to the switch rope hole 37; the second closing rope 20b on the floating plate 32 combines with the closing rope rod 28a and the first closing rope 20a tied to the rod and moves the same distance; the second closing rope 20b passes through the second closing rope hole 34b upward, then passes through the pressure rope ring 40 next to the first closing rope hole 34a, and then passes through the switch rope hole 37 at the lower end of the water collecting gate 14, and is fixedly connected to the switch rope hole 37. Before the flood discharge ditch 1 implements the engineering system of this case, it receives the flood water from the plateau path with a constant area capacity until the plain area. In this process, the flood discharge ditch 1 can only change the flow rate, overflow the water that exceeds the capacity of the ditch body, and let it flow freely in the land environment outside the ditch body. However, the introduction of the engineering system in this case has transformed the plain flood discharge ditch 1, especially at the place where the plateau path discharges water, realizing timely and effective control and treatment of the change in flow rate and the amount of water expanded. As long as the water does not overflow the ditch, this precious opportunistic water resource can be effectively retained. Based on the characteristics of potential energy flow, when the water flows downward, it carries more substances on both sides and the flow rate is slower, while the water carries less substances in the middle and the flow rate is faster. According to the principle that "the clearer the water, the better the flow performance", when the water flows to the pebble pit 11, it will inevitably flow into the pit. The pebbles 13 in the pit play a filtering role, and directly transport the filtered clean water to the floating object lifting chamber 19. The water level in the floating object lifting chamber 19 is stable, ensuring the smooth rise of the floating plate 32. The rising action of the floating plate 32 then drives all the floating rods and rope structures installed thereon to rise synchronously. In order to ensure the stable working ability of various floating rods on the floating plate 32, the rod heads of each floating rod are carefully designed to pass through the perforations on the two chamber partitions 17. This design ensures that there will be no jamming when the floating rods and ropes move up and down in the door opening and closing chamber 15. The two door opening rope rods 31 pass through the two door opening rope holes 33 respectively, and are each tied with the first door opening rope 22a and the second door opening rope 22b. A rope pressing ring 40 is provided next to the door opening rope hole 33, and the first door opening rope 22a and the second door opening rope 22b need to pass through the rope pressing ring 40.The first door opening rope 22a passes through the rope ring 24 upwards and ends in the door opening and closing rope pulling hole 37 at the upper end of the water collecting door 14; the second door opening rope 22b passes through the rope pressing ring 40 and directly passes into the door opening and closing rope pulling hole 37 at the lower end of the water collecting door 14, and also ends at the pulling hole. Through the action of the rope pressing ring 40, the door opening rope, which was originally loose rope, becomes tightened under the action of the rope pressing force. Under the tightening force of the upper and lower door opening ropes, the water collecting door 14 can be opened smoothly during the rotation of the hinge 21. The whole system has achieved effective management and utilization of flood resources through careful design and optimization. The door closing rope rod 28a passes through the first door closing rope hole 34a and is tied with the first door closing rope 20a. The first door closing rope 20a passes vertically upward through the corresponding rope ring 24, and the rope ring 24 is installed on the top 46 of the door opening and closing chamber. Subsequently, the first door-closing rope 20a continues to pass through the door-opening rope pulling hole 37 at the upper end of the water-collecting door 14 and is fixedly terminated at the hole. The second door-closing rope 20b passes through the second door-closing rope hole 34b and then passes through the rope pressing ring 40 located next to the first door-closing rope hole 34a, and then passes through the door-opening rope pulling hole 37 at the lower end of the water-collecting door 14 and is also fixedly terminated at the hole. When the floating plate 32 rises, the door-closing rope rod 28a and the second door-closing rope 20b rise at the same time, and the tension of the first door-closing rope 20a and the second door-closing rope 20b is completely relaxed; and when the floating plate 32 falls, the door-closing rope rod 28a and the second door-closing rope 20b fall at the same time, and the tension of the first door-closing rope 20a and the second door-closing rope 20b is directly applied. Under the rotation of the hinge 21, the water-collecting door 14 is closed. This switching process is achieved by alternately relaxing and tightening the door opening rope and the door closing rope 20, that is, when one rope is relaxed, the other rope is tightened, and vice versa, thereby controlling the opening and closing of the water receiving door 14.

[0041] By adopting the above technical solution, the present invention has the following beneficial effects: (1) By installing a rope hoisting ring and a rope stabilizing ring on the top and side wall of the switch door chamber, the impact of the flood entering the pipe on the rope is effectively prevented, the working efficiency of the rope is improved, and the stability of the entire system is enhanced. (2) Through the carefully designed floating rod structure and rope layout, combined with the use of a rope pressure ring, the water collection door is smoothly opened and closed, and the convenience of operation is improved.

[0042] like Figure 9-18The figure shows a further implementation scheme of the present application, in which a first locking hook 41a with a hook body pointing downward is provided at the end of the locking hook rod 27; in an initial state, the first locking hook 41a hooks downwardly onto the locking door circle 23 at the lower end of the water receiving gate 14; after the floating plate 32 rises, the first locking hook 41a escapes from the locking door circle 23; a locking detachment rope 39 is fastened to the end of the unhooking rod 26; a second locking hook 41b with a hook body pointing upward is fastened to the end of the unhooking rope 39 away from the unhooking rod 26; the unhooking rope 39 is arranged in the stabilizing rope circle 25 and the hanging rope circle 24; in an initial state, the second locking hook 41b is hooked upward into the locking door circle 23 at the upper end of the water receiving gate 14; after the floating plate 32 rises, the unhooking rod 26 rises accordingly, causing the unhooking rope 39 to loosen, thereby causing the second locking hook 41b to fall down by its own weight and escape from the locking door circle 23.

[0043] It is particularly important to install wind-resistant devices for the rotating switch doors set in the natural environment. The edge of the door frame of the water collection door 14 is equipped with a lock door ring 23. According to the design concept of the natural way adopted by the system of this project to avoid natural disasters, the opening and closing lock operation of the water collection door 14 also follows the natural principle. The core operation is that the entire system is built on the entire floating plate 32, through the forward and reverse movement operation, and accurately controls the time allocation of the program steps. The water flow first enters the pebble pit 11 to ensure that the floating object lifting chamber 19 receives the water source first. The lock hook rod 27 is an upright floating rod that passes through the lock hook rod hole 38 of the two chamber partitions 17 on the floating plate 32. The rod head of the lock hook rod 27 is connected to the lock hook 41 with the hook body downward, and the lock hook 41 can hook the lock door ring 23 at the lower end of the water collection door 14 frame downward. Once the floating plate 32 rises slightly, the downward lock hook 41 can quickly break away from the lock door ring 23 and continue to rise with the floating plate 32. When the floating plate 32 falls back to the bottom of the floating object lifting chamber 19, the lock hook 41 with the hook body downward will penetrate into the lock ring 23 again to lock the water receiving door 14. Another unhooking rod 26 is also installed on the floating plate 32, and it passes through the unhooking rod hole 36 on the two chamber partitions 17. The rod head of the unhooking rod 26 is tied with an unhooking rope 39, and the other end of the unhooking rope 39 is connected to the lock hook 41 with the hook body upward. The unhooking rope 39 is arranged according to the Fig.18 and Fig.17The instructions are arranged in the stabilizing rope ring 25 and the hanging rope ring 24 of the side wall 47 and the top 46 of the switch door chamber. When the floating plate 32 rises, the unloading hook rod 26 rises accordingly, causing the unloading lock rope 39 to loosen, so that the lock hook 41 falls due to its own weight and detaches from the lock door ring 23. When the floating plate 32 falls back to the bottom of the floating object lifting chamber 19, the lock hook 41 will be lifted by the unloading lock rope 39 and penetrate into the lock door ring 23 again to achieve the locking of the water receiving gate 14. This engineering system cleverly utilizes the phenomenon that water flows smoothly after entering the pebble pit, providing protection for the water receiving gate 14 to avoid flood impact damage. After being filtered by the pebbles 13 in the pebble pit 11, the water quality of the flood becomes more stable and the quality is improved. This design not only provides an appropriate path for the water flow, but also ensures the sequence of movement of each structure of the system and the precise execution of the steps, thereby ensuring the stable operation of the entire system.

[0044] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) The technical scheme drives the floating plate to rise and fall through the natural phenomenon of water flowing into the pebble pit and flowing smoothly, thereby controlling the opening and closing of the water collecting gate. This design enables the system to respond to environmental changes efficiently without the need for an external power source, thus achieving natural resource utilization and energy conservation and emission reduction. (2) Through the design of the locking hook rod and the unhooking rod, combined with the movement of the floating plate, the water collecting gate can be reliably locked and unlocked. This design not only ensures the stability of the water collecting gate under the impact of floods, but also automatically restores it to the locked state after the flood recedes, providing an effective protection mechanism for the system. (3) The technical scheme ensures the precise execution of the sequence of movement of each structure of the system and the steps through the carefully designed structural layout and time allocation control program steps. This not only improves the operating efficiency of the system, but also ensures the stability and reliability of the system. (4) The natural force of water flow and buoyancy is used to realize the automatic opening and closing operation of the water collecting gate, thus avoiding the environmental pollution and energy consumption that may be caused by traditional mechanical drive. (5) This technical solution has the ability to intelligently adapt to environmental changes and can automatically adjust the opening and closing degree of the water gate according to the water level and flow rate of the flood. After the flood recedes, the system can automatically restore to its initial state and prepare for the next flood. This automatic recovery function reduces the need for manual intervention and improves the intelligence level of the system.

[0045] like Figure 8 , 19 The figure shows a preferred embodiment of the present application, in which the total area of ​​the drainage holes 49 is smaller than the total water inlet area of ​​the water filter plate 18 .

[0046] In the engineering system of the present application, the function of the original flood discharge ditch 1 is modified on site. The position of the sewage water delivery pipeline 10 is exactly at the same horizontal plane as the floating lifting chamber 19. In order to solve the problem of the descent of the floating plate 32 in the floating lifting chamber 19, two drainage holes 49 are opened below the isolation plugging plate 48 between the sewage water delivery pipeline 10 and the floating lifting chamber 19. The sum of the areas of the two drainage holes 49 is smaller than the sum of the water inlet areas of the water filter plate 18, thereby ensuring that the rising ability and energy of the floating plate 32 are maintained. The aperture of the drainage hole 49 is designed to be larger than the aperture of the water filter plate 18. This design ensures the engineering quality of the floating plate 32 and effectively prevents the floating lifting chamber 19 from excessive internal pressure due to excessive water inflow. In addition, a section of mesh 12 is opened at the upper end of the plugging plate 48. This measure can assist the floating lifting chamber 19 to drain excess water, further ensuring the stable operation of the system.

[0047] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) By ensuring that the total area of ​​the drainage holes is smaller than the total water inlet area of ​​the filter plate, the rising capacity and energy of the floating plate are effectively maintained, thereby ensuring that the system can operate continuously and stably. (2) The aperture of the drainage hole is designed to be larger than the aperture of the filter plate. This design not only ensures the engineering quality of the floating plate, but more importantly, effectively prevents the floating lifting chamber from causing excessive internal pressure due to excessive water inflow, thereby protecting the safety of the system. (3) A mesh grating is provided at the upper end of the isolation plugging plate to assist the floating lifting chamber in draining excess water, further ensuring the stable operation of the system and extending the service life of the system. (4) The technical scheme has carried out on-site transformation of the function of the original flood discharge ditch. By adding an isolation plugging plate and drainage hole between the sewage water pipeline and the floating lifting chamber, the effective separation of sewage and floating objects is achieved, thereby optimizing the performance of the engineering system.

[0048] like Figure 2-7 As shown in Figures 22-23, a further embodiment of the present application is provided with ditch wall cement supports 51 on both sides of the flood discharge ditch 1; the ditch wall cement supports 51 are filled with crushed stones 54; the ditch wall cement supports 51 include ditch surface wall panels 52 and support beams 53; the ditch surface wall panels 52 are provided with two for limiting the crushed stones 54; the support beams 53 are arranged between the ditch surface wall panels 52; and it also includes a meshed rainwater grate 8 with a switch door; the meshed rainwater grate 8 with a switch door is arranged on the road surface above the ditch wall cement supports 51.

[0049] On both sides of the flood discharge ditch 1, there is usually a highway 4. In order to ensure the cleanliness and safety of the public road environment, this project system cleverly designed the layout of the rainwater conveyance pipeline 9 and placed it under the public road environment. On both sides of the flood discharge ditch 1, the original ditch walls made of broken rocks were demolished and replaced with ditch wall cement supports 51. These supports 51 are directly installed at the position of the original ditch wall to ensure that the discharge volume is consistent with the original design. The ditch wall cement support 51 is exquisitely constructed, with two ditch surface wall panels 52 as vertical frames, and each layer is equipped with three support beams 53 as cross beams, forming an upper, middle and lower three-layer structure. The ditch surface wall panels 52 and the support beams 53 are cast into one piece through cement, ensuring the stability and durability of the structure. On the top layer of the support, we laid a sidewalk 3 level with the original ground, and installed a rainwater grate 8 with a mesh and a switch door to replace the existing permeable grate 7, so as to effectively collect and discharge the potential ground rainwater resources outside the flood discharge ditch 1, while ensuring the water quality of the water pipeline. On the middle-layer support beam 53, a rainwater water pipeline 9 is placed, and its bottom edge is aligned with the horizontal position of the bottom of the flood discharge ditch 1, which can quickly absorb, divert and unload the rainwater 2 flowing down from the plateau potential, and collect the potential rainwater resources outside the flood discharge ditch 1 along the road. On the third-layer support beam 53, we placed a sewage water pipeline 10. The initial pipe mouth of the sewage water pipeline 10 is blocked by a plugging plate 48, and buried in the ditch side land 6 at the bottom of the flood discharge ditch 1, realizing the connection with the domestic sewage pipeline 5 on the side of the original flood discharge ditch 1. This design effectively solves the contradictory relationship between the original domestic sewage and the environment. Each support layer is equipped with at least three support beams 53, which are used to support the trench wall cement support 51 composed of two trench wall panels 52. After installation, we use the original trench wall gravel 54 removed to fill the gap between the support and the pipe, thus forming a stable overall structure, so that floods cannot shake the combination of trench wall cement support 51, rainwater water pipe 9, sewage water pipe 10 and gravel 54.

[0050] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) The ditch wall cement support adopts a cement casting structure of the ditch surface wall plate and the support beam, forming a stable and durable three-layer support system, which effectively improves the overall stability of the flood discharge ditch and can resist the impact of floods. (2) The design of the rainwater grate with a mesh and a switch door can effectively collect and discharge the potential ground rainwater resources outside the flood discharge ditch, while ensuring the water quality of the water supply pipeline. The setting of the rainwater water supply pipeline can quickly absorb, divert and unload the rainwater flowing down from the plateau potential, thereby improving the rainwater discharge efficiency. (3) The ingenious layout of the sewage water supply pipeline, by blocking the initial pipe opening with a plugging plate and burying it in the soil at the bottom of the ditch, realizes the connection with the domestic sewage pipeline, effectively solves the contradiction between domestic sewage and the environment, and improves the surrounding environment. (4) The crushed stone after the demolition of the original ditch wall is reused and filled in the gap between the support and the pipeline, which not only forms a stable overall structure, but also saves the cost of building materials, reflecting the environmental protection concept of resource recycling.

[0051] Example 2 exist Figure 1-3 In the above, the ground outside the flood discharge ditch 1 is used to collect water from the water source with a low position by using a permeable grate 7 which is level with the ground, which is an indispensable and important facility for rainwater resource engineering. Fig.24 In the structure of the load-bearing cast iron water-permeable grate 7, we can clearly see that its structure and function are relatively simple and open. The cast iron grate ribs 57 mainly bear the load-bearing function, while the cast iron drain holes 58 are in a non-selective open state and have no screening effect on the quality of the water flowing in.

[0052] In order to ensure the water quality of the overall engineering system and the capacity of the plain water collection and storage project, we decided to use a rainwater grate 8 with a mesh and a switch door to directly replace the original permeable grate 7. This replacement is based on an in-depth analysis of the shortcomings of the existing system and an urgent consideration of the need for improvement.

[0053] The system disclosed in this application is a key link in connecting plateau water flow and plain rainwater resource collection and storage projects. Its performance directly determines the effect of the plain rainwater resource collection and storage project. In view of the decisive role of the system in this case on the subsequent engineering capacity, we considered and planned a set of possible pollution cleaning and sorting facilities in the initial design stage of the system.

[0054] like Figure 25-31The figure shows a further embodiment of the present application, including a rainwater grate body 59; an upper mesh grate 55 is arranged at the upper end of the rainwater grate body 59 for filtering large pieces of garbage; a cast iron permeable grate 7 is arranged between the rainwater grate body 59 and the upper mesh grate 55 for bearing weight; the permeable grate 7 includes a cast iron grate frame 56, cast iron grate strips 57 and cast iron drain holes 58; the cast iron grate frame 56 is rectangular, a plurality of cast iron grate strips 57 are arranged at intervals, and the cast iron grate frame 56 is provided with a plurality of cast iron grate strips 57 ... The gap between the grate rib 57 and the cast iron grate bar rib 57 is the cast iron drain hole 58; the rainwater grate body 59 is also provided with a rainwater grate drain hole 61, and the position of the rainwater grate drain hole 61 corresponds to the cast iron drain hole 58 in the vertical direction; the side wall of the rainwater grate body 59 is provided with a door shaft rod hole 63; it also includes a barrier door 64 and a door shaft rod 66; the barrier door 64 is provided with a door shaft ring 65; the door shaft ring 65 is coaxially arranged with the door shaft rod hole 63; the The door shaft rod 66 penetrates into the door shaft rod hole 63 and the door shaft ring 65; it also includes a corner platform 68; there are two types of corner platforms 68, namely a first corner platform 68a and a second corner platform 68b; the first corner platform 68a is provided with a fixing rod through hole 69 and a water permeable hole 70; the second corner platform 68b is provided with a water permeable hole 70; the rainwater grate body 59 is provided with a mounting hole 62, and the first corner platform 68a and the second corner platform 68b are fixed to the rainwater grate body 59 through the mounting hole 62 Inside the grate body 59; the first corner platform 68a is installed on the corner platform mounting hole 62 at the lower end of the door shaft 66; the second corner platform 68b is installed on the corner platform mounting hole 62 on the other side; brushes 71 are provided on both the first corner platform 68a and the second corner platform 68b; it also includes a water tank 75, which is arranged below the rainwater grate body 59; the water tank 75 is connected to the rainwater grate body 59 through the water permeable hole 70; the bottom of the water tank 75 is provided with a bottom drainage hole 76.

[0055] At the upper end of the main body 59 of the rainwater grate, an upper mesh grate 55 is provided, whose function is to filter large pieces of garbage and ensure that they cannot enter the drainage holes 61 of the rainwater grate. Below the upper mesh grate 55, the original cast iron permeable grate 7 bears the load-bearing task, and its load-bearing function ensures the flat use of the upper mesh grate 55 and prevents it from being damaged. The flatness of the upper mesh grate 55 is conducive to mechanical cleaning, thereby effectively controlling the amount of load-bearing materials on the surface of the object-blocking door 64. The main body 59 of the rainwater grate is made of discarded recycled old plastics, and the drainage holes 61 of the rainwater grate correspond one-to-one with the cast iron drainage holes 58. This not only realizes the reuse of waste, but also solves the problem of waste plastic degradation occupying arable land. The door shaft rod 66 passes through the door shaft rod hole 63 on one side of the rain grate body 59, passes through the door shaft ring 65 of the object-blocking door 64, and then enters the door shaft rod hole 63 on the other side, so that the object-blocking door 64 is movably suspended at the water receiving port at the upper end of the rain grate drain hole 61 of the rain grate with mesh and switch door 8. There are two designs of the corner platform 68, and the table tops are all covered with 1mm water-permeable holes 70. One corner platform table top has a fixed rod through hole 69 and water-permeable holes 70, while the other has only water-permeable holes 70. The corner platform 68 is installed in the corner platform installation hole 62 of the frame of the rain grate body 59, and is located on both sides of the rain grate bar 60. In the corner platform mounting hole 62 of the rainwater grate strip edge 60 below the gate shaft rod 66, a corner platform 68 with a fixing rod through hole 69 is installed; and in the corner platform mounting hole 62 of the rainwater grate strip edge 60 without the gate shaft rod 66 below, a corner platform 68 with only a water permeable hole 70 is installed. Brushes 71 are attached to the corner platforms 68 on both sides. After testing, the coordinated use of the corner platform 68, the brush 71 and the water permeable hole 70 achieves the best water collection effect. The round stick-shaped brush 71 is placed close to the facade of the corner platform 68, and forms a concave angle with the facade of the corner platform 68 and the upper surface of the brush 71. When the downstream water flows through the facade, it will be close to the concave angle. Here, the water cannot flow out naturally (especially in a small water state), and can only infiltrate or flow down by superimposing and squeezing. The brush 71 is located above the water-permeable hole 70, and the natural density of its bristles helps the water-permeable hole 70 to filter out particles that are larger than the density of the bristles, causing them to roll out of the brush body. The mud and sand in the downstream water are intercepted by the brush and retained in the brush body, thereby preventing the mud and sand from forming hard mud balls on the corner platform 68. The brush body of this structure is easy to loosen and fall off when encountering cement sand, and flow out of the brush with water. However, soil particles smaller than 1 mm can easily pass through the water-permeable hole 70 with water and enter the water tank 75. It is worth noting that there are only two 2 mm bottom drainage holes 76 at the bottom of the water tank 75, so 1 mm particulate matter cannot be retained after entering the water tank, thereby ensuring the purity of the water in the tank, and thus not affecting the normal operation of the rainwater grate float 74 in the tank.

[0056] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) By introducing a rainwater grate with a mesh and a switch door to replace the original permeable grate, the system adds a screening function for the quality of the incoming water. The upper mesh grate can effectively filter large pieces of garbage and prevent them from entering the drainage system, and the design of the cast iron drainage hole and the rainwater grate drainage hole, combined with the permeable holes and brushes on the corner platform, can further filter out silt and fine particles, significantly improving the water quality of rainwater resources entering the plain for storage. (2) The main body of the rainwater grate is made of recycled waste plastic, which not only realizes the reuse of waste, but also improves the durability of the system. The cast iron permeable grate 7 ensures the load-bearing function, prevents the upper mesh grate from being damaged, and maintains the stability of the system. (3) The corresponding design of the rainwater grate drainage hole and the cast iron drainage hole ensures that rainwater can flow smoothly into the system and improves the efficiency of rainwater collection. At the same time, the design of the corner platform and the brush 71 optimizes the water flow path, prevents the formation of hard mud balls on the corner platform, and further ensures the collection of rainwater. (4) The flatness of the upper mesh is conducive to mechanical cleaning, which can effectively control the amount of load-bearing materials on the surface of the barrier door, reducing the workload and difficulty of manual maintenance. At the same time, the corresponding design of the rainwater grate drain hole and the cast iron drain hole makes the system easy to clean and maintain, reducing management costs.

[0057] like Figure 25-41 The figure shows a further embodiment of the present application, which further comprises a pull rope 72, a rain grate float 74 and a float rod 73; the rain grate float 74 is arranged in the water tank 75, the float rod 73 is arranged on the rain grate float 74, and its upper end passes through the fixed rod through hole 69; the object blocking door 64 is provided with a pull rope hole 67, one end of the pull rope 72 is tied in the pull rope hole 67, and the other end is connected to the float rod 73; the top of the water tank 75 is provided with a water tank buckle 77, which is used to be stuck on the bottom edge of the corner platform 68 to make the water tank 75 firmly connected to the rain grate main body 59. The object blocking door 64 is installed at the water receiving port at the upper end of the rain grate drain hole 61 through the activity of the door shaft rod 66. One end of the pull rope 72 is fixed in the pull rope hole 67 of the object blocking door 64, and the other end is connected to the float rod 73. After passing through the fixing rod through-hole 69 of the corner platform 68, the floating rod 73 is installed or adhered to the rain grate floating block 74, which is located inside the water tank 75. The object blocking door 64 is designed to open downwards, and is fixed to the upper end of the water receiving port through the door shaft 66 as a lever balance fulcrum. The rain grate floating block 74 is used as a counterweight, and its weight is increased as much as possible to ensure that when the floating block floats up, the door pulling force is reduced to zero, thereby realizing the automatic opening of the door.

[0058] The two sides of the rainwater grate strip 60 are tightly clamped by the two corner platforms 68 fixed in the corner platform mounting holes 68 to form a stable whole. The width of the water tank 75 is based on the sum of the bottom edges of the two corner platforms 68 and the width of the rainwater grate strip 60. Water tank buckles 77 are provided on both sides of the box mouth of the water tank 75 to fix the bottom edges of the corner platforms 68 to ensure that the water tank 75 is firmly installed under the rainwater grate strip 60. In the case of water accumulation at the grate mouth, the water flow is blocked by the obstruction door 64 and can only penetrate into the grate body through the low side gap of the door, and then flow to the brush 71 on the corner platform 68. After being filtered by the brush 71, the water continues to flow to the water permeable hole 70 on the corner platform 68. Since the diameter of the water permeable hole 70 is 1 mm, water can easily pass through and directly enter the water tank 75. The water in the water tank 75 generates buoyancy, causing the rainwater grate float 74 to rise, thereby driving the float rod 73 to rise. The rise of the float rod 73 causes the pull rope 72 to relax, and at this time, the door rope hole 67 is close to the fulcrum of the door shaft rod 66. Since the weight of the rainwater grate float 74 plays a major role in the control of the object-blocking door 64, the relaxation of the pull rope 72 causes the object-blocking door 64 to lose balance at the fulcrum of the door shaft rod 66, and the side without the pull rope rotates and falls due to its own weight, thereby realizing the door opening and draining. When the accumulated water in the water tank 75 is completely drained through the 2mm bottom drainage hole 76 at the bottom, the rainwater grate float 74 and the float rod 73 connected thereto fall. The tightening of the float rod 73 causes the pull rope 72 to generate tension on the object-blocking door 64, pulling it back to the original equilibrium position, thereby closing the rainwater grate 8 with the mesh belt switch door. The design of the corner platform installation hole 62, the door shaft rod hole 63, the object blocking door 64, the door shaft ring 65, the door shaft rod 66 and the corner platform 68 all follow the principle of dispersion and re-combination, so that the entire rainwater grate with mesh and switch door 8 is easy to repair and replace parts, avoiding the entire scrapping due to minor collision damage. The water collection capacity of the water tank 75 depends on the dense 1mm water permeable holes 70 on the corner platform 68, whose total area is larger than the total area of ​​the two 2mm bottom drainage holes 76 at the bottom of the water tank, ensuring that the water collection capacity of the water tank 75 is always greater than the drainage capacity, thereby maintaining the buoyancy of the rainwater grate float 74 and the water quality in the water tank 75.

[0059] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) The technical scheme realizes the automatic opening and closing function of the rainwater grate with a switch door by designing a linkage mechanism of the rainwater grate float, the float rod and the pull rope. When water accumulates in the water tank, the rainwater grate float rises to drive the float rod and the pull rope to automatically open the barrier door to drain water; after the water in the water tank is emptied, the rainwater grate float falls, and the pull rope automatically pulls back the barrier door to close. This automated process greatly improves the operating efficiency and reduces the need for manual intervention. (2) Through the coordinated use of the upper mesh and the brush on the corner platform, large pieces of garbage and silt and other impurities are effectively filtered out, ensuring that the quality of rainwater flowing into the water tank is significantly improved. This double filtration design allows rainwater to be effectively purified during the collection process. (3) The stable connection design of the rainwater grate body, the corner platform and the water tank, as well as the weight configuration of the rainwater grate float, ensure the stability and reliability of the entire system. Even in extreme weather conditions, the system can maintain normal operation and effectively prevent rainwater flooding. (4) The technical solution follows the design principle of dispersion and reassembly, making each component easy to repair and replace. When a component is damaged, there is no need to replace the entire system, only the corresponding component needs to be replaced, which reduces the cost and difficulty of repair. (5) Through the design of automatic opening and closing, as well as the effective filtering function, the system not only improves the efficiency of rainwater collection, but also ensures the quality of the collected rainwater, providing a reliable guarantee for the subsequent use of rainwater. This helps to improve the utilization efficiency of water resources and promote sustainable development. (6) By comparing the total area of ​​the 1mm permeable holes on the corners of the water tank with the area of ​​the two 2mm drainage holes at the bottom of the water tank, the water tank naturally and perfectly preserves all its functions. (7) The overall system integrates the transmission of the floating block (buoyancy), the floating rod (clear movement direction), and the pull rope (pulling one move the whole body), each of which holds its position, and the solution is in place and solved step by step without disrupting the order, which is simple and effective to solve the problem of environmental disasters.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
